Training golf putter having a warning device

ABSTRACT

A training putter comprises a game rod and a warning device. The game rod has a shaft of a hollow tubular body made of an elastic and electrically conductive material. The warning device comprises a conductive rod, a buzzer, and a battery. The conductive rod is a metal rod and is provided with one or more insulation members. The conductive rod is disposed in the shaft such that the conductive rod is not in contact with the shaft. The conductive rod has a contact portion capable of making contact with the inner wall of the shaft at the time when the shaft is curved. The buzzer and the battery are fastened with the game rod such that the buzzer, the battery, the conductive rod, and the shaft form a loop at such time when the shaft is curved.

FIELD OF THE INVENTION

[0001] The present invention relates generally to a golf putter, andmore particularly to a training putter with a warning device.

BACKGROUND OF THE INVENTION

[0002] The golfing posture of a golfer is an important factordetermining the outcome of the golf game. Take the putter as an example.As a golf ball has reached the putting green, the golf ball is not faraway from the hole. In an attempt to roll the ball into the hole, thegolfer mush exercise an appropriate force and a body stability such thatthe shoulder and the arm joints act as the swiveling fulcrums, and thatboth arms and the putter form an integral body to move in a pendularmanner to roll the ball along a predetermined track into the hole.

[0003] In the course of putting, the golfer's hands and hips may takepart in the action subconsciously, thereby resulting in a change in theangle of the wrist joint or the elbow joint. Such angular change resultsin the instability of the stroking and the rolling of the golf ball.Both professional and amateur golfers need a constant training toimprove their putting posture.

SUMMARY OF THE INVENTION

[0004] The primary objective of the present invention is to provide atraining putter with a warning device capable of buzzing to remind agolfer of his or her improper putting posture.

[0005] In keeping with the principle of the present invention, theforegoing objective of the present invention is attained by a trainingputter, which comprises a game rod and a warning device. The game rodhas a hollow shaft which is made of an elastic and electricallyconductive material. The warning device comprises a conductive rod, abuzzer, and a battery. The conductive rod is a metal rod and is providedtherein with one or more insulating members for separating theconductive rod from the shaft. The conductive rod has a contact portion,which comes in contact with the inner wall of the shaft at such timewhen the shaft is curved. The buzzer and the battery are securelymounted on the game rod such that they form a conductive loop at thetime when the conductive rod and the shaft come in contact with eachother.

DETAILED DESCRIPTION OF THE INVENTION

[0010] As shown in FIGS. 1-3, a training putter 1 of the preferredembodiment of the present invention comprises a game rod 10 and awarning device 20.

[0011] The game rod 10 comprises a shaft 11, a game head 12, and a grip13. The shaft 11 is a hollow tubular body made of an elastic andelectrically conductive material containing carbon fiber. The shaft 11is of a tapered construction. The game head 12 is made of a metalmaterial and has a connection portion 121 which is provided with afitting hole 122 extending along the longitudinal direction thereof. Thebottom end of the shaft 11 is fitted into the fitting hole 122, therebymaking the game head 12 and the shaft 11 electrically conductive. Thegrip 13 is made of a rubber material and is fastened with the top end ofthe shaft 11.

[0012] The warning device comprises a conductive rod 21 which is made ofcopper and has an outer diameter smaller than the bottom end innerdiameter of the shaft 11. The conductive rod 21 is provided with threeannular insulation members 22, which are disposed in the shaft 11 fromthe top end of the shaft 11 such that the outer walls of the threeinsulation members 22 are in contact with the inner wall of the shaft11, and that the conductive rod 21 is located in the shaft 11, andfurther that the bottom end of the conductive rod 21 is jutted out ofthe bottom end of the shaft 11. The top end of the conductive rod 21forms a contact portion, which comes in contact with the inner wall ofthe shaft 11 at the time when the shaft 11 is curved by an externalforce. A battery mount 23 is located in a recessed portion of the gamehead 12 and is provided with a battery receiving cell 231 which isprovided in two opposite walls with a positive conductive piece 232 anda negative conductive piece 233. The positive conductive piece 232 isjutted out of the bottom of the battery receiving cell 231 to beconnected to the game head 12. A buzzer 24 is mounted on the batterymounted 23 and is provided with a positive input end 241 and a negativeinput end 242 which is connected to the negative conductive piece 233.The positive input end 241 is connected to the conductive rod 21. Abattery 25 is disposed in the cell 231 such that the positive and thenegative poles are respectively connected with the positive and thenegative conductive pieces 232 and 233. When the shaft 11 and theconductive rod 21 are in contact with each other, the battery 25, thegame head 12, the shaft 11, the conductive rod 21, and the buzzer 24form a loop, thereby enabling the buzzer 24 to make a buzzing sound as awarning signal.

[0013] As illustrated in FIG. 4, the training putter 1 of the presentinvention is used for putting in a pendular manner. If both arms of agolfer and the training putter 1 are kept in a linear state, theapplication force exerting on the training putter 1 is stabilized toprevent the curving of the shaft 11. As a result, the shaft 11 and theconductive rod 21 are not in contact with each other. The battery 25,the game head 12, the shaft 11, the conductive rod 21, and the buzzer 24remain in a circuit-breaking state. The buzzer 24 remains silent.

[0014] In the event that the wrists and the hips of the golfer moveimproperly to result in formation of another swiveling fulcrum by theelbow joint or the wrist joint. As a result, the grip 13 forms a newthrust point, which is responsible for a velocity difference that existsin the grip 13 and the game head 12 and causes the elastic shaft 11 tocurve. The shaft 11 and the conductive rod 21 are in contact with eachother so that the battery 25, the game head 12, the shaft 11, theconductive rod 21, and the buzzer 24 form a complete circuit. The buzzer24 makes a buzzing sound as a warning signal to remind the golfer of hisor her improper putting posture.

[0015] The embodiment of the present invention described above is to beregarded in all respects as being merely illustrative and notrestrictive. Accordingly, the present invention may be embodied in otherspecific forms without deviating from the spirit thereof.
